Safety Interlock Switches

Transcription

1 Safety Interlock Switches D4BL D4BL uard Lock Safety-Door Switch Release protective cover locks using controller signals or pushbutton switches after the cutting tool stops moving due to inertia A mechanical lock is applied automatically when the Operation Key is inserted. A high level of safety is achieved using a mechanism where the lock is only released when voltage is applied to the solenoid. Conforms to EN (TÜV) standards corresponding to the CE marking Certified by UL, CSA and CCC standards The Switch contact is opened by a direct opening mechanism (NC contacts only) when the protective cover is opened. Direct opening mechanism that is EN-certified is indicated by on the Switch Auxiliary release key ensures easy maintenance and unlocks the door in the case of a power failure. Tough aluminum die-cast body incorporating a switch box with degree of protection satisfying IP67, UL, and CSA TYPE6P, 13 Equipped with a horizontal and vertical conduit opening Models incorporating easy-to-see indicators for monitoring and those using an adjustable for a swinging door are available The mounting direction of the head can be changed to allow the to be inserted from four directions S Specifications Standards and EC Directives Conforms to the following EC Directives: Machinery Directive Low Voltage Directive EN 1088 Certified Standards Certification body TÜV Rheinland Standard EN (certified direct opening) S-ET-19 File No. R UL UL 508 E76675 CSA CSA C22.2, No. 14 LR45746 CQC (CCC) B Certified Standard Ratings TÜV (EN ), CCC (B ) Item Standard Model Indicator Model Utilization category AC-15 AC-15 Rated operating current (Ie) 3 A 6 A Rated operating voltage (Ue) 250 V 115 V Note: Use a 10 A fuse type gi or g that conforms to IEC as a shortcircuit protection device.
